CVE-2024-11374Network attack vector

Reflected script execution via unescaped redirect URL

Published Dec 7, 2024 · Updated Apr 8, 2026

Reflected cross-site scripting in Rellaco TWChat 4.0.4 and earlier allows remote attackers to execute scripts through a crafted URL. Addon_controller.class.php emits a remove_query_arg-generated URL without context-appropriate output escaping. No authentication is required, but a user must follow the attacker's link; the script then runs in the victim's browser and can read or alter page data.
